Economic Importance for Humans: Positive
Between 3 and 3.5 million pounds of Menippe mercenaria claws are harvested annually in Florida alone. This occupation employs around 4,000 crabbers in Florida, as well as many restaurant employees along the eastern sea-board. Federal law mandates that only one claw per crab be removed (it will grow back in 1-2 years), and that the claw must be at least 6.99 cm (2 and 3/4") from the first joint to the tip of the lower immovable finger. Overall, the stone crab industry generates 12-15 million dollars from Florida to North Carolina.
